I started to hack together an ICQ (old protocol v.5) module for netfilter but it was still-born due to insufficiencies with the NAT/helper framework. Specifically, (before newnat -- I have not looked at newnat yet, but it supposedly solves the problems) only "single-shot" expectations were available. But even after I worked past that, with helpers that reset the expectation (kinda like the way old signal handling worked where one had to reset the signal in the handler), I found that a helper could have only one expectation active at a time. If a second expectation was triggered, the first one was dropped. Of course, a protocol such as ICQ's v.5 has multiple sub-channels going at once, one for each "direct connection" in fact. As such, it needs to be able to handle multiple related rules. But this was all for the v.5 protocol. Most people are using v.7 (or is it 8 already) now which is a completely different protocol (AOL AIM). I have no idea of it's workings and whether the same problems exist with it or not. b. -- Brian J. Murrell
